THREAD-BOARD LIFTER.

SPECIFICATION forming part of Letters Patent No. 740,250, dated September 29, 1903.

Application filed December 15, 1902. Serial No. 135,247. (No model.)

To all whom, it Wtay concern..-

Be it known that I, Nnncrssn N. S. DAUDE- the ring-rail is at the highest point of the wind, thelimited area of play subjecting the thread to abrasion as it passes through the guide-wire and ring-traveler.

Afurther object of this invention is to lessen the swing or ballooning ofthe thread when the ring-rail is near the bottom of the wind; and a final object is to attain this end by cheap and simple mechanism adapted to adjustment upon the common form of spinning or twisting frame.

To the above ends my invention consists in the novel'construction and combination of parts hereinafter set forth, and illustrated in the accompanying drawings.

Figure 1 is a transverse section of one side of a spinning-frame, showing the invention in side elevation and the thread-board in normal position; Fig. 2, a similar section of the same, showing the thread-board elevated and the actuating parts in side elevation. Fig. 3 is a vertical section of the thread-board and adjacent parts on line w m of Fig. '1, and Fig. 4 a front elevation of a section of therocking-arm rod and attached angle-rod. Fig. 5 is a front elevation of a portion of a spinningframe, showing the rocking-arm rod connections.

Like figures of reference indicate like'parts throughout the views.

This novel mechanism is adapted for use upon the common form of spinning or twisting frames 1, whereon are vertical spindles 2, driven by bands 3 from the drum 4. The ring-rails 5 are vertically movable to feed the thread to the bobbins 6 through the The usual rocker-rail 11 is fixed to the frame below the spindles. Parallel thereto, but in a higher plane longitudinally, reciprocates the usual rocking-arm rod 12, vibrated by the rocking arm or lever 26, fulcrumed to the rock-shaft 27. Also fixed to the'rockshaft is'the bar 28, carrying upon one extremity a weight 29 and engaging with its other extremity the lifting rod or poker 30. Fixed to the rocking arm is the chain 31, leading to the builder mechanism. It is in conjunction with these familiar parts that my mechanism is utilized.

To the lower face of the rocker-rail 11 is fixed by bolts 13 ,or otherwise a rearwardlyprojecting supporting-bar 14, upon which is fixed a vertical guide or fork 15, through which passes a lover or link 16, pivoted at one extremity to the supporting-bar and at the other to the link 17, which in turn has its extremity pivoted to the inner end of a forwardly-directed lever 18. The latter lever has fixed to its free end an upwardly-curved finger 19, carrying a terminal roller 20. The lever 18 is pivotally supported at a point in the rear of the finger 19 by-a downwardly-directed arm 21, fixed to the frame 1 adjacent the thread-board 9. The latteris hinged upon its inner margin to the frame 1, allowing its outer edge freedom to move upwardly and describe an arc. Upon the bottom of the thread-board and disposed transversely thereto is a metallic strip 22, with upturned marginal flanges, forming a channel in which the roller 20 travels.

The rocking-arm rod 12 has fixed to its front face by set-screws 23 a downwardlyprothe rise of the thread-board thereby regulated.

The rocking-arm rod, as is well known, vi brates with a longitudinal reciprocating motion, the time consumed in the advance or return of this rod being equal to the time consumed in the rise or fall of the ring-rail. The rod 12 in its advance stroke forces the traveler 7. The thread is supplied by the inclined surface of the angle-arm 24; against and upon the link 16, forcing the latter downward. This movement is communicated, through the link 17 and the lever 18, to the finger 19, which rises and through the roller 20 elevates the thread-board 19 and its attached guides to correspond with the rise of the ring-rail, the various parts assuming the position shown in Fig. 2. Obviously upon the return movement of the rocking-arm rod the link 16 gradually rises under the action of gravity as the angle-arm retreats and the thread-board approaches its lowest position, as shown in Fig. 1, which position, it will be noted, corresponds with the depression of the ring-rail. An ideal tension is thus automatically obtained upon the threads passing through the guides.

While my device is illustrated as applied to oneside of the spinning or twisting frame, it is intended for contemporaneous application to the other side also.

One of the valuable features disclosed is adaptability to frames in common use upon which adjustment is possible without material change of structure.

Having described my invention, what I claim as new,'and desire to secure by Letters Patent, is-

1. In a spinning-frame, the combination with the rocking-arm rod of an angle-arm fixed thereto,a hinged thread-board, a rockerrail, and a series of levers intermediate the latter and the thread-board adapted to be actuated by the contact of the angle-arm.

2. In a spinning-frame, the combination with the rocking-arm rod of an angle-arm fixed thereto, means for adjusting the anglearm vertically and longitudinally, a hinged thread-board, a rocker-rail, and a series of levers intermediate the latter and the threadboard adapted to be actuated by the contact of the angle-arm.

3. In a spinning-frame, the combination with the rocking-arm rod of an angle-arm fixed thereto, a hinged thread-board and a series oflevers below and contacting with the thread-board adapted to be actuated by the contact of the angle-arm.

4. In a spinning-frame, the combination with the rocking-arm rod of an angle-arm fixed thereto, means for adjusting the anglearm Vertically and longitudinally, a hinged thread-board, and a series of lovers below and contacting with the thread-board adapted to be actuated by the contact of the anglearm.

5. In a spinning-frame, the combination with the rocking-arm rod of a projection upon said rod, a hinged thread-board, and a series of levers below and contacting with the thread-board adapted to be actuated by the projection.

6. In a spinning or twisting frame, the combination with the rocking-arm rod of an inclined projection upon said rod, hinged thread-boards, and a series of levers below and contacting with the thread-boards adapted to be actuated by the inclined projection.

In testimony whereof I have affixed my signature in presence of two witnesses.
